And if it is a serious vegan who pursues "what you see is what you get," there may be different opinions. Once they have visually identified various ingredients, their respective tastes and the mixed multi-tastes will clearly Emerged in my mind. For the watch brand who must be most concerned about is the shooting team wearing a diving watch is what brand? And, this watch waterproof depth is how many meters? Do not know whether because the brand did not see this opportunity, so far no one brand claims that the movie worn in the diving shooting watches with their own. But in fact, for divers, the watch is one of the few effective props that can help them while diving. In addition to rotating the bezel can always remind the diver oxygen time, the dive indicator and the scale of the more shiny paint, can also be easily read in the deep sea. The most crucial point is that the extreme environment of deep-sea high pressure is also the best stage for watch brands to show their own watchmaking capabilities. As we all know, moisture, dust, magnetism and vibration is the watch's four enemies. In the 30s and 40s of last century, many watch brands in the field of waterproof competition. In 1927, Ms. Mercedes Gleitzes wearing Rolex Oyster swim across the Strait of England, a full 15 hours and 15 minutes, after the media coverage and advertising, make Rolex fame. The Omega launched Marine in 1932 and worn by adventurer Charles William Beebe, diving for the first time to a depth of 10 meters and setting the record. At the request of Pasha of Marrakesh, Louis Cartier created a watch that allowed him to know when it was swimming. The watch was fitted with a protective cap on the crown, attached to the watch case by a link, ensuring a winding crown Has excellent waterproof performance. With the continuous renovation of watchmaking technology, diving watch waterproof depth gradually increased, from 100 meters, 300 meters to the present 1000 meters, 2000 meters ... ... then the end of this figure is what? The answer is 11,034 meters, which is the depths of the deepest Mariana Trench sea depths of Richards, is also the ultimate goal of all diving equipment challenges. In the current record, in 1960, US Naval Captain Don Walsh and the Swiss inventor Jacques Piccard piloted the deep-sea submersible "Trieste" reaching a depth of 10,916 meters. The outer surface of the submersible, Fixed a specially designed Rolex Deep Sea Special watch. After the submersible surfaced, this watch is still accurate when it travels. And Bell & Ross's Hydromax Deep Sea diving table also claims to have 11,000 meters of water resistance. However, this watch is a quartz movement, the case is also filled with silicone oil to do the pressure buffer. I believe that for anyone who loves mechanical watches, it can not be regretted to see that it is in the middle of the world in any harsh environment. Rolex Deep Sea Snorkel Watch Pressure balanced helium valve Diving process, with the depth increases, the water pressure increases, the tiny helium atoms will be under the action of a strong pressure squeeze into the case from the cracks in the table, making the table pressure gradually increased in order to achieve a basic balance between internal and external pressure . When the diving after the dive up, the external water pressure decreases rapidly, and the case of helium atoms are difficult to rule out an instant, it will form a huge pressure difference, force enough to the top of the case. To solve this problem, all the dive tables will be equipped with helium row device to ensure watch safety. Adjustable strap Diving watch strap, usually made of solid steel or special materials, to minimize the corrosion of sea water. At the same time, many diving watch strap adopt adjustable design, such as Rolex DeepSea series, it's Glidelock buckle, adjustable width of 18 mm. Just open the clasp, you can see the inside of the middle with teeth clip, each grid 1.8 mm apart, a total of 10 grid. Professional divers can wear easily even wearing a 7mm wetsuit. Rotating bezel Due to oxygen limitations, a countdown reminder is crucial to the diver, and decompression sickness can occur if it is floating too fast due to oxygen shortages. Therefore, the rotating bezel is a clever and at the same time very useful function. Usually just turn the bezel while diving, the 0 bezel on the bezel on the minute hand, and then watch the minute hand to move the scale on the bezel to know the dive time. Of course, you can also countdown to use, first of all know your dive time, rotate the bezel will be minute marks on the minute hand, then minutes go bezel 0 scale time is your diving limit time. External bezel multi-turn is designed to be a single counter-clockwise direction, and now the latest design is more than one cut-out to control the bezel any rotation and lock. Ploprof's unique bezel button is set at 2 o'clock and features an orange plated aluminum bezel. Simply push the button to turn the bezel on either side and lock it in place to ensure it does not move during the dive. Ploprof also has a self-draining helium valve, which is set at 4 o'clock and emits helium atoms when depressurized. This feature is especially suitable for professional divers working on diving bells. Breguet Marine Royal Series rose gold alarm diving watch Deep water alarm Breguet's Marine Royal rose gold alarm snorkel diving watch, although the water depth of only 300 meters, it is commendable that it has deep-water alarm function, when the alarm rings, prompting people to return to the ground time. Luminous instructions We all know that light is easily dispersed in water and is not suitable for conduction. As a result, it is very dark below about 100 meters. Therefore, the surface of a dive watch is usually covered with a fluorescent material on the pointer, scale or surface, and the size of the pointer and scale are deliberately enlarged to make it easier for the diver to read. Luminescence needs to be made of radioactive material, the first commonly used radium, but due to excessive radioactivity has been changed to new safety materials. The half-life of this material does not exceed 10 hours. Turn into the crown As we all know, the crown is the only part of the outside world and the movement. In order to prevent water from entering the movement through the crown, watchmakers have developed a design called screw-in crown - the crown joined the rubber waterproof connection made of rubber, when the crown is tightened, The water is tightly cut off from the watch. There are also a lot of dive watches to upgrade, they not only have a larger crown, but also to add more deep groove treatment, make the operation more slippery and convenient underwater. At the same time, into the crown on the military form is widely used.
